Continuation section

[kyklish]

Related: #25

Official doc says:

Var =
(
A line of text.
By default, the hard carriage return (Enter) between the previous line and this one will be stored as a linefeed (`n).
    By default, the spaces to the left of this line will also be stored (the same is true for tabs).
By default, variable references such as %Var% are resolved to the variable's contents.
)

Current formatting:

Var =
(
    A line of text.
    By default, the hard carriage return (Enter) between the previous line and this one will be stored as a linefeed (`n).
    By default, the spaces to the left of this line will also be stored (the same is true for tabs).
    By default, variable references such as %Var% are resolved to the variable's contents.
)

All text inside parenthesis are indented, this is wrong. We lose user formatting.

Official doc says:
LTrim: Omits spaces and tabs at the beginning of each line. This is primarily used to allow the continuation section to be indented.

Question:

1. Maybe user must manually format such continuation sections and formatter never touch such sections?
2. Formatter can indent continuation sections, only if there LTrim right after open parenthesis?

{
    Var =
    ( LTrim
        A line of text with preserved    extra    spaces between words.
    )
    Var =
(
User formats this text as he needs.
  I need here only two spaces.
      But here six spaces    and four spaces between words.
)
}

How about implement formatting of continuation sections like in official documentation?

FileAppend, This is the text to append.`n ; A comment is allowed here.
    , %A_ProgramFiles%\SomeApplication\LogFile.txt ; Comment.

ProductIsAvailable := (Color = "Red")
    ? false
    : ProductIsAvailableInColor(Product, Color)

EDITED: Fully implemented in #260 PR
